Kara Iti Mō te Whakangākau Nui

Ko te kōhatu whakamāmātia tere he taputapu whakamāmātia pūmahara e hangaia ana kia wehe i te wera tere ake i te wā o ngā mahi whakamāmātia, ka pakaru rā anō hoki i te pirau o te wera ki te taonga me te kōhatu anō. Ko te nuinga o ngā pirau wera kei te whakamāmātia, i āwhinahia e te mākinakina i waenganui i ngā kapa whakamāmātia me te taumahi, e āwhina ana i te taonga e waru, e panonihia ai te tae, ngā panonitanga matū (pērā i te annealing i ngā metara), te pirau rānei o te kōhatu anō. Kei te whakatika a Quick cooling discs i ēnei rapanga tru ngā āhuatanga hoahoa e whai ake nei: he whare poro ki ngā ara honohono e āwhina ai i te hau me te kōkiri wera e rere ai, ngā taputapu whakawhitinga wera ki roto i te puku o te kōhatu (e nui ana ko te paranihi, ko te parauri rānei) e tango wera mai i te takotoranga whakamāmātia, me ngā kapa whakamāmātia kua tahuna ki ngā rīwai e herea ai te wera e mau ai te ahunga tikangia i ngā wā pānui. Ko ngā kapa whakamāmātia—ko te nuinga ko te ōksiti aruhiana mō ngā metara, ko te karaiti Ōki (silicon carbide) mō ngā taputapu kāore i te tōmeti—kei te wehe kia iti ake te rohe pānui, ka iti ake te mākinakina me te wera e hua ai. E raweke ana ēnei kōhatu mō te whakamāmātia i ngā taputapu e mōhiotia ai te wera pērā i te aruhiana, te parauri, ngā uhi metara, ngā pāpaku, me ngā wāhanga metara māmā, kei reira anō pea te whakarahinga iti rawa e āwhina ai i te tika o te āhua. Kei te hanga motuka, ka whakamahia hei whakamāmātia i ngā pōro aruhiana me ngā upoko silinda, e here ai i te waru e pa ana ki te mahi o te motuka. Kei te hāpori rererangi, ka whakapiripiria ai ngā wāhanga titanium me ngā uhi parauri, kei reira anō pea te pirau o te taputapu i ngā wero wera. Kei te hāpori hiko, ka whakapapa wāhanga pāpaku me ngā kauta kauwhata kāore e tanu, e rerekē ai ngā āhua māmā. Ko te āhua whakamāmātia tere anō ka roa ake te ora o te kōhatu tru te iti iho o te pirau wera ki te kaihere, e iti ai te wehe o ngā kapa me te pirau. Tru te pupuri i ngā wā pāpaku iti ake, kei te āwhina ake ēnei kōhatu i te tāpiripiri taputapu tika, ngā āhua māmā, me te iti ake i te tere o ngā taonga hou, na reira ko te taputapu matua mō ngā mahi whakamāmātia tika kei te tino hiahia ki te whakahaere wera.
